Sealed lead acid battery with charge regulator

The charge regulator is simple with double sided adhesive tape glued on the sealed lead acid battery. Also this should be only a temporary stopgap.

After I replaced the heavy bulky 20 Watt photovoltaic by a foldable 34 Watt Photovoltaic, next item to replace is the buffer battery.

On top of my wish list is a Lithium battery from Valence.

Photovoltaic
Different view points about photovoltaic from our different technical magazines as wide outstretched information about electric power from light.


Laptop supplied by solar power Laptop supplied by solar power
Notebooks can be easy supplied with solar energy. From solar electric power for a day on the beach, for expeditions up to island solutions for houses without power grid connection.


Batteries for 12V solar power supplies
Notebooks can be easy supplied with solar energy. From solar electric power for a day on the beach, for expeditions up to island solutions for houses without power grid connection.




  Photovoltaic for the mobile usage


34 Watt peak, foldable as a 2 kg package to pack in every backpack. In the case of working on the beach, in the mountains or on an expedition the ideal power supply.

12V power supply 12V power supply
At the 12V plug from the battery is a 3 plug connector for the AA battery charger of my Canon-S1, charger for the cellphone and car adapter for the notebook.


Office at the waterfall Office at the waterfall
To work has nothing to do with being cruel to yourself in a stuffy office. GPRS, UMTS and a solar power supply makes it possible to work in an inspiring environment.


What delivers a photovoltaic at sun behind clouds? What delivers a photovoltaic at sun behind clouds?
Behind a sparse cloud is the sun recognizably. My foot throws already the clue of a shadow. 0,8A charge current. 30% of the 34 Watt peak.






Backpack with notebook and accessories All the power supply fits in this small backpack. In front the belt for the notebook, the digital camera and the cellphone. In the backpack Normal, I would not take for some hours at the waterfall charger for the cellphone and for the AA cells from the camera. But here it's to show, what all is possible. Foldable photovoltaic module Such unapparent small, I take the folded 34 Watt module out of the backpack. With 2 kg weight, it produces with 2 hours sunshine the same amount of energy Unfold photovoltaic The photovoltaic module is next unfolded. Stil are no photovoltaic cells visible. Flap out the photovoltaic With the flap out, the width of the photovoltaic module increases from 44 to 88cm. A half squaremeter active area. Sealed lead acid battery with charge regulator The charge regulator is simple with double sided adhesive tape glued on the sealed lead acid battery. Also this should be only a temporary stopgap. Photovoltaic at strong cloudy sky Behind dense dark grey clouds is the sun invisible. The charge current changes from 0,39 to 0,65A or 14% to 24% of the 34 Watt peak rating. Sunny Through a hole in the clouds short time full sunshine. 2,23A charge current or 82% of 34 Watt peak. The PV lies not optimal oriented on the rock. Direct sun The foldable photovoltaic placed on an other place to align better towards the sun. The charge current climbs to 2,33A or 86% of 34 Watt peak. Blue sky - photovoltaic in the shadow The sun just disappeared behind the Untersberg. Only the blue of the sky illuminates the szene. Nevertheless delivers the photovoltaic still 5% peak. Flooded beach After some weeks rain, finally bathing weather again. But the beach is half flooded. Humans dense together, so the only place for the photovoltaic on a tree.
